摘　　要：火山岩气藏是天然气开发的全新领域，储层埋藏深、致密、非均质性强、气水关系复杂，国内外可借鉴的经验少，总体研究程度较低。通过徐深气田几年来的不断探索，在火山体和岩性岩相识别、储层预测、产能评价、压裂增产等方面取得了一定的认识，初步形成了火山岩气藏开发技术。研究认为受火山机构及多期喷发影响，火山岩储层错叠连片，岩性岩相复杂多变、非均质性强；单井产量较低、差异大，井控动态储量普遍较低；主要储集空间为气孔、溶蚀孔，其渗流特征反映为低渗储层；以水平井和直井联合开发的方式，可实现Ⅰ、Ⅱ类储层的有效动用。Volcanic gas reservoir development is a firenew field, with deep buried and tight reservoir, strong heterogeneous, complex gas-water relationship, minor referable experience from foreign country, and generally low research degree. This paper obtained some understandings in respects to the identification of volcanic body, lithology and lithofaeies, reservoir prediction, productivity evaluation and fracturing stimulation etc. , preliminarily forming the development technologies for volcanic gas reservoirs. The research indicates that the volcanic reservoirs are crossed and stacked, with complex and variable lithology and lithofacies, strong heterogeneous, low single-well production, significant differences, general low dynamic well-controlled reserves. The accumulation space is dominated by gas pore and emposieu, and it belongs to low permeability reservoir according to its seepage features. Type Ⅰand type Ⅱ reservoirs can be effectively developed by the combination of vertical well and horizontal well.
